IMPsovEMENT 1N oX-YOKBS.

To ALL wHoM 1T MAY coNcERN:

4 Be it known tha-tI, CHARLES H. POST, of Guilford, in the county of'N'ew Haven, and State of Connecticut', have inventeda new and useful Improvement in OX-Yokes; and I do hereby declare that the following is afull, clear, and exact description thereof, which will enable `those skilled in the art to make and use the same, reference being had to the accompanying drawings forming part of this specification.

The object of this invention is to provide a permanent fasteningto the bows of oX-yokes, or a substitute` for the key or pin which is in ordinary use for that purpose; and the invention consists in attaching a hinged metallic `plate to the yoke, the end of which engages with the bow in such a manner that the bow is securely fastened thereby, as I will proceed to describe. I i

Figure 1 represents a top view of the yoke, snowing the fastening-plates as they are attached to the yoke.

Figure'' is a longitudinal section of the same, through the line a; x of iig. 1, showing the manner in-which the plates are applied. l

Similar letters of reference indicate corresponding parts.

A represents the yoke, .B represents the bows, and C the fastening-plates. There is nothing peculiar or Vnovel in the formation or construction of the yoke or the hows, except that inthe bows there are notches instead of. key-holes, as seen in the drawing. l The metallic plate C is made in the form of a hinge, one portion of which is fastened to the yoke with screws, or in any substantial manner, and it is so placed on the yoke that the other (or loose) end laps over the bow-hole in the yoke, as seen in tig. 1. When the bow is 'introduced into the yoke, its end raises the fastening-plate until the end of the plate drops into the notch in the bow, when, by drawing down the bow, it assumes the position seen in fig. 2, thus securely holding the bow in place. a is a small knob on the plate for the purposeof more easily handling or adjusting it.

These fastening-plates may be made 'of iron or any other suitable metal, and of any convenient size and shape.

Having thus described my invention, I claim as new, and desire to secure by Letters Ilatent- The metallic plate C, constructed and operating substantially as shown and described, in combination with the yoke A and the bow` B, as and for the purposes set forth.

CHARLES H. POST.
